Borla 140085 Cat-Back Exhaust System (40085)

best muffler if you want a straight through powerful flow and nice deep tone. i put one of these style catbacks on a jeep many years ago and also gave it great sound.

Exactamente como lo esperaba, un sonido ni muy fuerte ni muy bajo, claro si quito los catalizadores se escuchariabmas fuerte.

Put this one my 14 chev 1500 with the 5.3 about a month ago. 3rd cat delete and all new 3" piping. Absolutely love the sounds, quieter then I anticipated though.

Todo excelente buen servicio y calidad

I enjoy them...!I used my Borla 40085 mufflers in conjunction with a Borla 60548 X-pipe and a pair of Vibrant 17390 resonators on my 2011 BMW X5 50i.I don't like the sound of muffler deletes on these vehicles and I have tried different combinations of mufflers and resonators or just resonators alone, but this one works the most like what I was looking for with a nice low pitched rumble upon acceleration that turns into a sporty (not obnoxious) rasp at the top end.Highway cruising lets you know the engine is there with a pretty light hum, but it doesn't interfere with music or conversation and it certainly doesn't drone or induce a headache of any kind.When you put your foot down the engine note is obvious both inside and out, but again it is not overwhelming for you or passersby.After close to a year, I still saw these are worth the money, but I am being forced to install a pair of Helmholtz chambers to kill the humming that occurs from between just off idle to about 2000rpm.The XR1s do well overall, but the drone never went away and it is the only thing detracting from the experience of owning them. Once the Helmholtz chambers are installed the excess sound pressure between 70-130hz will be neutralized and cruising will really be sublime...!They're still worth every penny...!
